排隊理論

產生exponential分布的 inter-arrival time，Mean 0.25, 0.5, 1, 2

1.統計並劃出Cumulative distribution曲線與其理論曲線

2.時間單位各為1、2、…20單位，分別統計各時間單位之arrival的個數，並劃出Pn(t) v.s t 與其理論值，n取0、1、2、3、4、5，λ取0.5。-Queuing theory produce exponential distribution of inter-arrival time, Mean　 0.25, 0.5, 1, 2 1. Cumulative distribution statistics and draw the curve with its theoretical curve 2. Each unit of time is 1, 2, ... 20 units, respectively, each time statistics the arrival of the number of units, and draw Pn (t) vs t and its theoretical value, n take 0,1,2,3,4,5, λ is 0.5.
